La Paz, 11,000 feet, M. Cardenas, April 29, 1922 (wo. 48, spe- 

 cial). Species very near H. hirsuta, but differing in glands and 

 indumentum and in form and relative dimensions of the floral 

 parts. Flowers white, streaked with blue. A shrub 2 meters 

 high. 



Hoita hirsuta 



Densely pilose with short white divergent hairs. Branches 

 ascending, flexuous, nodose, dark-colored, terete but strongly 

 nerved. Stipules mostly reflexed, 5 to 8 mm. long, regularly acu- 

 minate from the base to the acute summit. Petioles 2 to 3 cm. 

 long, slender, the petiolules 3 mm. long, the rachis about 3 times 

 as long. Leaflets 3 to 6 cm. long, 8 to 16 mm. wide, the terminal 

 not much longer than the lateral, all lanceolate with acutish base 

 and long-acuminate and acute summit, entire, thickish, densel}^ 

 and minutely black glandular-dotted on both sides, minutely 

 hairy, the strongly ascending secondaries 8 or more on a side, 

 slender, the venation obscure. Peduncles stout, longer than the 

 rachis, which is densely flowered, the flowers imbricate, nearly 

 sessile. Calyx-tube campanulate, mostly somewhat inaequilat- 

 eral, about 4 mm. long and 3 nun. broad, 5-ribbed, with about 10 

 nerves, the suliulate acuminate acute teeth about half as long. 

 Vexillum light blue, obovate, 1 cm. long, 4 mm. broad, the base 

 gradually tapering. AVings a little longer than the vexillum and 

 the keel, and of the same color, adnate to the keel almost to the 

 summit. Free portion of keel deep-purple, concave, obtuse, the 

 base short-auriculate, the Avings with long linear-attenuate 

 caudae nearly half as long as their claws. Filaments coherent 

 nearly four fifths of their length. Ovary irregularly obovoid, 

 densely glandular-puberulent, the slender style white, slightly 

 thickened and flattened upward. 



Pongo de Quime, 11,500 feet, 0. E. White, July 12, 1921 {no. 

 154). 



Parosela pilocarpa 



Glabrous, with the exception of the densely long-pilose in- 

 florescence. Stems very slender, the branchlets widely spread- 

 ing, terete. Leaves nearly sessile, the rachis about 2 cm. long, 

 the leaflets mostly 9, opposite, nearly sessile, 3 to 5 mm. long, 

 1.5 to 2 mm. wide, oval or slightly obovate, with rounded summit 

 and obtuse base, entire or almost imperceptibly crenulate, thick.
